SYNOPSIS
#include <corosync/cpg.h>
int cpg_membership_get(cpg_handle_t handle, struct cpg_name *groupName,
struct cpg_address *member_list, int *member_list_entries);
DESCRIPTION
The cpg_membership_get function is used to determine the current pro‐
cesses in the configuration. You probably will not need to call this
function much as one of the first confchg callbacks you will get will
be from the cpg_join() function containing your process. The argument
handle is used to reference the cpg instantiation. The argument group‐
Name will return the name of the group The argument member_list will
return the list of processors in the current membership. The argument
member_list_entries should be set with the size of member_list and will
return the size of the member_list after return from the function.
ERRORS
The errors are undocumented.
